To all fwltomc't may concern.'

lBe it known that we, ANNA BELLE ALLEN and LEoNARD DAY, citizens of the United States, and `residents of the borough of Manhattan, city, county, and' State of New York, have invented certain new and useful Improvements in Telephone Sets, of which the following is a specification.

rlhis invention relates -to telephone sets, particular] ofthe desk or portable type, which preferably comprise a transmitter, a receiver,local circuits, a controller for said circuits subject to the 'control of the user, and a suitable structure for combining the parts of each set.

One object of this invention is to form an efficient and reliable structure for a telephone set which will lend itself readily as the -mechanical adjunct to Various ornamental designs)I A further object is to provide for inclosed circuit connections and controlling means.

More particularly an object is to provide a hollow base member and inclose circuit con-- trollers therein.

A further Objectis to operate said controly v1ers by means of a movable receiver sup-porting'platform designed to overlie said hollow base member.

It is also an object of this invention to provide an efficient and reliable controller mechanism.

AAnother object is to provide a supplemental v'casing for the receiver which will coperate in furthering the general object of this invention, while other objects will be apparent from the following description, and will be more particularly set forth in the claims.

Referenceshould be had to the accompanying drawings forming part of this specification, illustrating an embodimentof this invention, and in which:

Figure 1, isa sectional elevation, showing an embodiment of this` invention; Fig. 2 is a bottom plan view of the embodiment shown in Fig. 1; Fig. 3 is a fragmentary sectional elevation similar to Fig. 1 but with the receiver removed; Fig. 4 represents'a section through line 4 4 of Fig. 3 and looking in the direction of the arrow; Fig. 5 is a fragmentary sectional elevation of a modification; Fig. 6 is a bottom plan view of the modification shown in4 Fig. 5 but with .the bottom closure removed; Fig. 7 is a` diagram showing .the 'local circuits,

Referring now more particularly to the drawings 1 designates a hollow base member, preferably of conducting material, such as cast metal. This member may be of any suitable out-line, but it is preferred that it be ring shaped, as shown inV Figs. 1 to 4 inclusive. In Figs. 5 and 6 this member is of an irregular .three lcornered outline as shown. Extending from the upper portion of base 1, and forming a part thereof, are two inwardly project-ing ledges 2 and 3. At o posite sides of ledge 2 are formed ribs 4, W ich are perforated, as shown, to receive a pin 5, which passes through two lugs 6, formed near one edge of a tilting platform 7, so that this tilting platform 7 is' hinged to the base 1. The plat-form 7 preferably overlaps the base 1,1as shown, and is cutaway at 8 directly overithe ledge 2. `Secured to the ledge 2 and extending upwardly therefrom is a tubular support 9 of conducting material; fixed to t-he upper' end of the standard 9 is a hollow transmitter casing 10 which is pro- Patentcd Apr. 1, 1913.

vided-with a passage 11, connecting with the passage `1.2 of s upport 9, so as to complete a continuous passage from the transmitter 13, which may be of standard type, to the interior of theclaollow base member 1.

14.- is a removable member forming a combined diaphragm guard and mouth piece for the transmitter 13. The member 14 may be secured to the casing 10 by any suitable means, such as the screws 15, as illustrated. The tubular support 9 is preferably so formed ythat the transmitter 13 and the members 10 and 414 approximately overlie the center of the base member 1 so as to insure stability of the entire structure.

Secured to the under face'of ledge 3 by any suitable means, such as a screw 16, is a spring member 17, which bears against the under face of the tilt-ing platform 7 and tends to elevate the same until the projecting portions 18 are rotated into contactwith the upper edge of the base 1. The portions 18 form mea-ns' for limiting the upward movement or upward tilting of the platform 7. The spring means 17 is embodied preferably as illustrated inthe form of a leaf spring and is electrically connected to the conducting hase member. 1. `This spring i 19 is placed upon the surface of the platform 7, this platform will be depressed until it engages with the upper face of the base member 1, which forms means for limiting its downward movement. Secured by suitable means, such as the screws 20 in a recess 21 formed in the lower face of the ledge 3 is an insulating plat-e 22. The lower surface of this plate is preferably'ush with the surface 23 yto which' the spring 17 is secured. Fixed to theinsulating .plate 22 are two spring contacts 24 and 25 which overlap each other, as shown, and prefer-l ably extend at right angles to the spring 17 .K The contacts 24 and 25 arey respectively provided with binding posts 26 and 27.` Adjacent to the binding post-s 26 and 27 arerespectively two pairs of binding posts 28 and 29, the binding posts of each'pair being connected by conductingpieces 30 and 31.

The spring 17 and the spring contacts 24 and 25 are respectively provided'with contact points 32, 3,3 and' 34. vThese contact points are preferably in alinement, as shown, and are out of contact one with another with the apparatus asis shown in Figs.' 1 and 7. With the apparatus as-shown in Fig. 3 the contact point 32 is in connection with .con-l tact point 34, and contact point 33 is in contact with contact point 34. As diagrammatically indicated in Fig. 7 the transmitter 13 is permanently connected to the spring. 17. The members 14, 10, 9 and 1 are respectively employed in making up this connection,l one terminal of the transmitter' being connected to the piece 14, although in the diagram of Fig. 7 certain connections from the'transmitter 13 to the controlling apparatus in the base 1 comprise the conducting standard 9,.it vis to be understood 'that any suitable connections for the'transmitter 13 may be provided and connected in anyY manner well known in the art, `the support 9 being shown as provided withl va connector passage 12, see Fig. 1.

The receiver 19, preferably of the disk type,-illustrated, is provided with a supple-y mental .casing 35. This casing 35 is recessed to lreceive the receiver 19 which abuts against the 'shoulder 36, and is held fast thereto bythe screw 37, as illustrated. This casing 35 serves to protect the receiver 19 and readily adapts itself to any desired ornamentation.' Receiver 19 may be of standard type.

The base 1 may be provided with a bottom closure which is illustrated in Fig. 5. This closure is indicated by 38, vand is secured to the base 1 by means of screws 39 engaging lugs 40. 'It is to be understood that a similar closure to that illustrated 'in l Fig. 5 may be provided for the base shown in Figs. 1 to 4 inclusive.

The contour of the base member shown in Y grammatically shown in Fig. 7. When lnot Figs. 5 and 6 makes it preferable to locate the ribs 4 and the lugs 6 at- `the corners 48. With this construction the ledge 2 may be dispensed with since the tubular support 9 enters the base portion 1 from the side,.as shown. In any event it is preferred that the tubular support vor standard 9 be located adjacent to the hinge 4, 5, and 6 of the tilting platform 7. This location of tubular support 9 makes it impossible to place the receiver 19 directly over the hinge for' the tilting platform. On the other hand it is most convenient to place'this receiver near the middle of the tilting platform, in which event, its weightwill have sufficient leverage about the-pin 5 properly to' operate the spring 17 41 designates an insulating bushing extending through' the wall' of the base 1; while 42 designates a similar bushing extending through the ledge 2 adjacent to the tubular support 9. Suitable insulated leads 43 constituting limiting circuit connections' for the receiver 19-may extend through the bushing 42 and be connected to the binding posts on the insulating plate 22. The bush-A ing 41 provides an outlet for the three local' line wires designated by 44,l 45 and 46v in Fig. 7. The local connections for a telephone set,- suchasthat described, are dia-y n y in use the receiver. 19 is normally resting; upon the platform 7, so as to depressthe combinedvspring and contact'device 17, in which case the line rwire 44 is connected to spring 17 over the path which may be traced v10o as follows: line wire 44, binding posts 28, wire 47, transmitter 13, 'supporting structure 9, etc., to spring 17 l 7 Line wire 45 is connected to springcontact 24 by binding post 26. 105

Line wire 46 is irst connected to one of the bind-ing posts 29 the other of which 4posts is connected to one terminal of the receiver 19. The other terminal of the receiver 19 is connected to binding post 27, -1'10 which in turn is connected-to spring contact 25.

When it is desired to usethis telephone set the receiver 19 is removed from the plat-4 form 7, whereupon spring 17 causes a Ine- 11.5 chanical and electrical connect-ion between the contact points 32, 33 and 34. Itis to be understood that the local line wires 44, 45 and 46 lead to apparatus well known in the art, the circuits likewise bein of approved 1.20 type. Furthermore it is to ie understood that various embodiments and modifications of this invention are contemplated and that what has been shown and described isfor the purpose of illustration.
